CHURN-IDASHER.

i Specification of Letters Patent. i Patented Sept. 19, 191 6,

Application filed July 7, 1916. Serial No. 108,022.

I '0 all whom it may concern:

Be it known that I, FRANK XV. HARMON, a citizen of the United States, residing at Buxton, in the county of York and State of Maine, have invented certain new and useful Improvements in Churn-Dashers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in dashers for churns and consists of a simple and efficient device of this nature, having two sections which slide together to expand the same to engage the churn to hold the same in place, a reverse movement being imparted to the dasher sections serving to release the same.

My invention comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

I illustrate my invention in the acompanying drawings, in which:

Figure l is a central vertical section through the churn showing the dashers locked in place therein. Fig. 2 is a section showing the dasher sections detached and withdrawn from the churn, and Fig. 3 is a sectional view on line 33 of Fig. 1.

Reference now being had to the details of the drawings by letter, A designates the body of a churn having pintles A and A fastened to the circumference at points diametrically opposite, and B is a handle fixed to the pintle A said pintles being adapted to be mounted in suitable bearings, not shown, and whereby the body may be rotated.

At the open end of the churn is a circumferential flange C underneath which one end of the dasher section is adapted to contact. The dasher is made up of two interlocking rack sections, one of which is made up of the longitudinally disposed and inclined bars E which pass through apertures in a cross bar D, being held theret y pins E and also a cross bar E with apertures for the reception of the bars which are fastened by means of pins E. The other dasher section comprises a rack made up of longitudinal bars G which pass through cross bars N and are held thereto by means of pins 0. The bars G move freely through inclined apertures in the cross bar E with the exception of the central bar which passes through the cross bars D and E at right angles thereto. It will be noted that the cross bar D has inclined apertures F intermediate the bars E which are for the reception of the adjacent ends of the bars G when the two sections are pushed together in the manner shown in Fig. l of the drawings, while other apertures S are formed in the sections N and are adapted for the reception of the adjacent ends of the sections E. By having the bars of the two sections or racks inclined relative to one another, it will be noted that, when they are pushed together, they will be moved laterally so that the outer ends of the bars N will frictionally engage the inner surface of the churn and hold the dasher in place, while the upper ends of the bars E will engage underneath the flange C.

What I claim to be new is 1. In combination with the body of a churn, a dasher made up of two interlocking sections which are adapted, as the sections are moved longitudinally, 'to expand laterally to engage the wall of the churn.

-2. An extensible dasher for churns comprising two racks made up of longitudinal bars with apertures therein, thevbars of one rack movable through apertures in the other, said bars disposed at inclinations to each other and extended to open laterally so that the rack sections will frictionally engage the wall of the churn.

3. A dasher for churns made up of two racks comprising cross bars with apertures therein and longitudinal bars, the bars of one rack movable through the cross bars of the other, said bars disposed at inclinations to each other and adapted to move laterally as the sections are pushed together, the ends of the cross bars being adapted to engage the inner surface of the body of a churn.

4. In combination with a churn having an interior flange adjacent to its open end, a dasher made up of two sections, each having cross and longitudinal bars, the bars of one In testimony whereof I hereunto afiix my rack IlOVablQ through apertures in the other; signature in presence of tWo Witnesses. said ars disposed at inclinations to eac other, forming means whereby, as the sec- FRANK HABMON' tions are moved together, the outer ends of Witnesses:
